This is one of the best recorded concerts we've ever seen; undoubtedly because of the stature of the honoree, everyone involved outdid themselves. Diana Krall's masterful "Down With Love" with her trio is gobsmacking right off the bat. Glee stars Lea Michele, Kristin Chenoweth, and Matthew Morrison belt out "My Man" and "One Less Bell to Answer/A House Is Not A Home," while Tony Bennett shows what lyric interpretation is all about with Charlie Chaplin's "Smile." LeAnn Rimes and BeBe Winans duet on "Come Rain or Come Shine" (with Jeff Beck on lead guitar), Stevie Wonder and trumpeter Arturo Sandoval improvise on "People," Faith Hill solos wistfully on "Send in the Clowns," and Seal does amazing things with "Guilty." And for the finale, Barbra sings two beautiful songs by Marilyn and Alan Bergman ("Windmills of Your Mind" and "The Promise")—exquisitely.
